 Because you have the structural problem then of a white guy, like the whitest guy ever, the whitest guyest guy ever, overtaking the first black woman vice president. I don't see that really happening. I just don't think it works. Joe Biden's wanted to be president since he was in the womb. I don't think he's going to give it up willingly. They probably have to invoke the 25th Amendment if they wanted to drag Biden out of there. And even then, they'd probably have to drag him out cold on a stretcher.
